Sound and Light
This is what sound needs to travel through.
What is a medium? (Matter will count as well.)
Particles in a solid do this.
What is vibrate?
This type of heat transfer happens when particles collide and transfer energy in solid. (Through direct contact.)
What is conduction?
When a sound wave reflects off of a surface, it is called this.
What is an echo?
This process allows plant cells to use sunlight to make food.
What is photosynthesis?
This is the type of wave that requires a medium to travel.
*Hint I am NOT asking for an example of this type of wave. I want to know the overall term for this type of wave.
What is an electromagnetic wave?
This phase of matter has the MOST amount of kinetic energy.
What is a gas?
When the particles in a substance slow down enough, the substance may change from a liquid to this phase.
What is a solid?
A wave with more amplitude has more of this.
This type of change creates a new substance with different properties, like when wood burns.
What is a chemical change?
This part of the electromagnetic spectrum is what we can see.
What is visible light?
As a gas is heated, its particles do this, causing the gas to expand.
What is move faster and spread apart?
The transfer of heat through liquids or gases by the movement of currents is called this.
What is convection?
An electromagnetic wave is distinguished by it's ability to travel in one of these.
What is a vacuum?
The layer of gases that surrounds Earth and supports life is called this.
What is the atmosphere?
This part of the wave determines color?
What is frequency AND wavelength?
The average kinetic energy of all the particles in a substance.
What is temperature?
This type of heat transfer does not require matter and can happen through space (without touching).
What is radiation?
This type of wave transfer can cause light to turn into thermal energy.
What is absorption?
This law states that matter cannot be created or destroyed in a chemical reaction.
What is the law of conservation of mass?
With light, frequency determines color. With sound, this is what is determined by frequency.
What is pitch?
The movement of particles is the result of the amount of this type of energy in the particles. *Hint: I'm not talking about Kinetic Energy!
What is thermal energy?
A material that slows down heat transfer, like wool or Styrofoam, is called this.
What is an insulator?
What is refraction?
This type of friction occurs when an object moves through air.
What is air resistance?
